Abstract:
The second part of the First Byurakan Survey is aimed at detecting all
bright (B<16.5) UV-excess starlike objects in a large area of the sky.
By comparison with other major surveys such as the ROSAT All Sky
Survey (Cat. IX/10, the ROSAT WGACAT (Cat. IX/12) catalogue of
point sources, the IRAS (Cat. II/125) survey, the 6cm Green Bank
(Cat. VIII/52, the 1.4GHz NRAO VLA (Cat. J/AJ/115/1693, and the
92cm Westerbork Northern sky surveys (Cat. VIII/62) and with the
catalogue of mean UBV data on stars, we estimate the number of AGNs
present in the FBS survey and its completeness. We have made
spectroscopic observations of nine of the most promising FBS
candidates. We have found six new QSOs, bringing the total number of
known QSOs in this survey to 42. By comparison with the Bright Quasar
Survey, we found that the completeness of this last survey is of the
order of 70% rather than 30-50% as suggested by several authors.
